flicking will be less effective?

The official blog says about handling: Rapid steering inputs, such as techniques that rely on ‘flicking’, will be less effective on race days, as a more aggressive driving style will result in overheating the tyres and faster wear.

I wonder what this is intended to mean. Is it an admission that flicking is actually faster? Or is it that flicking has a very bad effect on race day? If so, why is it written as "less effective"? Isn’t flicking always slower in F1? There was a lot of talk about drifting being faster in F1 24. As someone who wants realistic handling, this expression bothers me quite a bit.
